Optogenetics is one of the most powerful tools in neuroscience, allowing for selective control of specific neuronal populations in the brain of experimental animals, including mammals. We report, for the first time, the application of optogenetic tools to human brain tissue providing a proof-of-concept for the use of optogenetics in neuromodulation of human cortical and hippocampal neurons as a po
Background and aims The simultaneous measurement of many proteins is now possible using multiplex assays. In this pilot study we investigated a total of 124 proteins in plasma from chronic myeloid leukemia (CML) patients with the purpose of identifying proteins that are differently expressed at diagnosis and after tyrosine kinase inhibitor (TKI) treatment initiation. Methods Samples were taken fro
Background: The use of mapping algorithms have been suggested as a solution to predict health utilities when no preference-based measure is included in the study. However, validity and predictive performance of these algorithms are highly variable and hence assessing the accuracy and validity of algorithms before use them in a new setting is of importance. The aim of the current study was to asses
InAs nanowires (NW) grown by MOCVD with diameter d as small as 10 nm and gate-All-Around (GAA) MOSFETs with d = 12-15 nm are demonstrated. Ion = 314 μA/μm, and Ssat =68 mV/dec was achieved at Vdd = 0.5 V (Ioff = 0.1 μA/μm). Highest gm measured is 2693 μS/μm. Device performance is enabled by small diameter and optimized high-k/InAs gate stack process. Device performance tradeoffs between gm, Ron, a
Familial aggregation (clustering) of venous thromboembolism (VTE) is the clustering of VTE within a family. Though several genes, such as antithrombin, protein C, protein S, factor V, and prothrombin are associated with the familial clustering of VTE, these loci only partially explain the familial aggregation of VTE. The epidemiology of the familial aggregation of VTE exhibits typical characterist
The ability of biological molecules to replicate themselves is the foundation of life, requiring a complex cellular machinery. However, a range of aberrant processes involve the self-replication of pathological protein structures without any additional assistance. One example is the autocatalytic generation of pathological protein aggregates, including amyloid fibrils, involved in neurodegenerativ
OBJECTIVES: To estimate risks of fatal/nonfatal coronary heart disease (CHD), stroke and cardiovascular disease (CVD) with SBP in an observational study of patients with type 2 diabetes. METHODS: Twelve thousand, six hundred and seventy-seven patients aged 30-75 years, treated with antihypertensive drugs, without previous congestive heart failure, followed for 5 years. RESULTS: Risk curves of CHD
BACKGROUND: Multiple sclerosis (MS) is a chronic inflammatory autoimmune disease of the central nervous system (CNS). One potential therapeutic strategy for MS is to induce regulatory cells that mediate immunological tolerance. Probiotics, including lactobacilli, are known to induce immunomodulatory activity with promising effects in inflammatory diseases. We tested the potential of various strain
Background Preventive measures are needed to counteract the increasing burden of cutaneous malignant melanoma (CMM). As a basis for rational melanoma prevention, we investigated geographic differences and impact from socioeconomic factors related to incidence, clinical stage at diagnosis and outcome. Material and methods All patients with primary invasive CMM diagnosed in 2004-2013 in the southern
Both road traffic noise and air pollution have been linked to cardiovascular disease. However, there are few prospective epidemiological studies available where both road traffic noise and air pollution have been analyzed simultaneously. The aim of this study was to investigate the relation between road traffic noise, air pollution and incident myocardial infarction in both current (1-year average
Multiple genetic hits are detected in patients with acute myeloid leukemia (AML). To investigate this further, we developed a tetracycline-inducible mouse model of AML, in which the initial transforming event, overexpression of HOXA10, can be eliminated. Continuous overexpression of HOXA10 is required to generate AML in primary recipient mice, but is not essential for maintenance of the leukemia.
OBJECTIVE: There is great need of biomarkers for research and clinical purposes in COPD. This study explored the relationships between ten putative plasma biomarkers of COPD and physiological measures of reduced lung function. METHODS: FEV(1), FVC, residual volume/total lung capacity (RV/TLC) and CO diffusion capacity (D(L)CO) were assessed in 357 subjects from the Swedish Twin Registry. The l
CYP3A metabolic activity varies between individuals and is therefore a possible candidate of influence on the therapeutic outcome of the tyrosine kinase inhibitor imatinib in chronic myeloid leukemia (CML) patients. The aim of this study was to investigate the influence of CYP3A metabolic activity on the plasma concentration and outcome of imatinib in CML patients.
Cripto has been known as an embryonic stem (ES)- or tumor-related soluble/cell membrane protein. In this study, we demonstrated that Cripto has a role as an important regulatory factor for hematopoietic stem cells (HSCs). Recombinant Cripto sustained the reconstitution ability of HSCs in vitro. Flow cytometry analysis uncovered that GRP78, one of the candidate receptors for Cripto, was expressed o
BACKGROUND: There have been few reports on the long-term outcome of comminuted radial head fractures in adults. METHOD: 10 women and 9 men with a mean age of 45 (21-65) years when they sustained a comminuted fracture of the radial head were re-evaluated after 15-25 years. 6 patients had been nonoperatively (NO) treated while 13 had had a radial head excision. The uninjured elbow served as a contro
Retroperitoneal sarcomas are rare and treatment should optimally be centralized. Despite successful centralization with 90% of the patients referred prior to surgery, delays occur, which led us to assess lead times in a population-based series. Method. Patients diagnosed with retroperitoneal sarcoma in the southern Sweden health care region 2003-2009 were eligible for the study. Data on referrals
